1. Outline

Integration between the MS2690A/MS2691A/MS2692A or MS2830A Signal Analyzer and the AWR

Visual System SimulatorTM

Simulation Software supports efficient design of communication systems.

<Main Purpose>

Design integrating hardware with simulation

Wireless communication standards test

Integrated simulation with circuit and end-to-end simulation

RF component specification R&D

The system supports easy design in cooperation with test and simulation processes using a signal

analyzer/vector signal generator, as well as effective optimization of RF components and overall system

performance.

Using simulation based on actual measurement data reduces the amount of design and prototyping work,

cutting R&D time and costs. Moreover, it can help match performance to requirements, preventing

over-specification waste and cutting product costs.

This solution also supports faster product time-to-market (TTM), helping beat competitors and cutting

costs.

This application note explains system design using the Signal Analyzer and Visual System SimulatorTM

simulation software, the setup procedure, how to integrate with the Visual System SimulatorTM

, and gives

an example of amplifier module system simulation using LTE FDD Uplink test signals.

1.2. MS2690A/MS2830A Signal Analyzer Series

Since the MS2690A/MS2830A Signal Analyzer series support the Vector Signal Generator

(MS2690A/91A/92A option-020 and MS2830A option-020/021), digitizer function, and waveform memory

required for TRx simulation measurement validation all in one unit, a measurement environment is quick

and easy to establish.

The digitizing function of Signal Analyzer corrects instrument errors automatically as shown in Figure 1-1,

eliminating troublesome calculation using correction data and validation of correction data. The digitized

waveform data can be used with simulation tools.

Figure 1-1. Digitizing Function

1.3. Visual System SimulatorTM Software by AWR

The Visual System SimulatorTM

software is a communication system/radar simulator tool using a

block-element GUI. Marketed under the tradename of AWR ConnectedTM

for Anritsu, this solution

supports integrated operation between Visual System SimulatorTM

, the Signal Analyzer, and the Vector

Signal Generator using a system block-element GUI (TestWave™ software) to set and control the

measuring instruments for testing via an external interface such as Ethernet. Installing the software

supports simple integration between the validation and simulation processes using an actual

measurement unit.

1.4. Integration between Signal Analyzer and Visual System SimulatorTM

Figure 1-3 shows an integrated design image for an RF component (DUT: Device Under Test) using the

Signal Analyzer and Visual System SimulatorTM

.

The baseband IQ waveform data of the simulation evaluation signal generated by Visual System

SimulatorTM

is downloaded to the Vector Signal Generator and simulation signals are output for

evaluation like from a Vector Signal Generator. The actually tested DUT output signal is captured by the

Digitizer of Signal Analyzer. This digitized data is fed-back for verifying the simulation design cycle.

Linked control of the Signal Analyzer is made easy via the Ethernet interface using Visual System

SimulatorTM

.

It supports easy design in cooperation with test and simulation processes using a signal analyzer and

vector signal generator for efficient optimization of RF components and overall system performance.

4. Amplifier Module System Simulation using LTE FDD Uplink

This section introduces an example of system simulation for an amplifier module using LTE FDD Uplink

test signals.

4.1. System Diagram

Figure 4-1 shows the system diagram.

Figure 4-1. System Simulation for Amp Module using LTE FDD Uplink Test Signals

Using the LTE FDD Uplink test signal created by Visual System SimulatorTM

, the amplifier module

simulation is analyzed for comparative evaluation with the actual measurements using measuring

instruments.

The DUT design model block is an amplifier module design created using the Microwave Office® circuit

simulation software.

On the other hand, the LTE FDD Uplink test signal baseband IQ waveform data is downloaded to the

Vector Signal Generator to input the same signal to the tested amplifier module as at simulation. The

amplifier module signal output is digitized by the Signal Analyzer. The measured data is fed-back to the

simulation to analyze the prototype amplifier module characteristics by simulation.

.

Figure 4-3 shows examples of spectrum, constellation, CCDF, and EVM graphs. The results indicated by

the blue lines in these graphs are the analysis results for actual data for the amplifier module prototype.

5. Summary

Repeated verification of design simulations and actual prototypes at the first stage of system design is

costly in both time and money.

Using actual measurement data in simulations including assumed conditions and unknown elements can

help effective optimization of the performance of RF components and the communication system overall.

This solution uses integrated operation of the MS2690A/MS2691A/MS2692A, MS2830A, and Visual

System SimulatorTM

software to optimize design of communication systems. Simulation is made easy by

using actual measured data obtained through integrated control of the measuring instruments from output

of evaluation signals to capture of actual measured data.
